How to estimate the magnetic field of an exoplanet Posted: 20 Nov 2014 11:18 AM PST Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value of the magnetic moment of the planet HD 209458b.

It's filamentary: How galaxies evolve in the cosmic web Posted: 20 Nov 2014 10:34 AM PST How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? Astronomers now propose some answers. The researchers highlight the role of the 'cosmic web' -- a large-scale web-like structure comprised of galaxies -- on the evolution of galaxies that took place in the distant universe, a few billion years after the Big Bang.

Quantum mechanical calculations reveal the hidden states of enzyme active sites Posted: 20 Nov 2014 10:34 AM PST Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as 'active' sites. But scientists lack basic information about their function because the states thought to be critical to their chemical abilities cannot be experimentally observed. Now, researchers have reported the first direct observation of the electronic states of iron-sulfur clusters, common to many enzyme active sites.

New technique allows ultrasound to penetrate bone, metal Posted: 20 Nov 2014 08:34 AM PST Researchers have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these so-called 'aberrating layers.'

Scientists discover novel metamaterial properties within hexagonal boron nitride Posted: 20 Nov 2014 08:32 AM PST Researchers have demonstrated that confined surface phonon polaritons within hexagonal boron nitride exhibit unique metamaterial properties that enable novel nanoscale optical devices.

Versatile bonding for lightweight components Posted: 20 Nov 2014 08:32 AM PST New materials are making cars, planes and all sorts of other things lighter. The catch is that many of these materials can't be welded. Now there's an alternative joining method available -- gradient adhesives provide an extremely good way of ensuring joined parts stay joined for their entire service life and hold up well in the event of a crash.

Riddle of the missing stars: Hubble observations cast further doubt on how globular clusters formed Posted: 20 Nov 2014 08:32 AM PST Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are very similar to those found in the Milky Way, and so must have formed in a similar way.

A path to brighter images and more efficient LCD displays Posted: 20 Nov 2014 06:16 AM PST Engineers have developed a polarizing filter that allows in more light, leading the way for mobile device displays that last much longer on a single battery charge and cameras that can shoot in dim light.

Hand dryers can spread bacteria in public toilets, research finds Posted: 20 Nov 2014 05:21 AM PST Modern hand dryers are much worse than paper towels when it comes to spreading germs, according to new research. Airborne germ counts were 27 times higher around jet air dryers in comparison with the air around paper towel dispensers.

Unravelling the mystery of gamma-ray bursts with kilometer-scale microphones Posted: 20 Nov 2014 05:19 AM PST A team of scientists hopes to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'. It's hoped the kilometer-scale microphones will detect gravitational waves created by black holes, and shed light on the origins of the Universe.

New computer model predicts gut metabolites to better understand gastrointestinal disease Posted: 20 Nov 2014 05:17 AM PST The first research to use computational modeling to predict and identify the metabolic products of gastrointestinal (GI) tract microorganisms has been published by researchers. Understanding these metabolic products, or metabolites, could influence how clinicians diagnose and treat GI diseases, as well as many other metabolic and neurological diseases increasingly associated with compromised GI function.

NASA's Swift mission probes an exotic object: 'Kicked' black hole or mega star? Posted: 19 Nov 2014 02:50 PM PST Astronomers have discovered an unusual source of light in a galaxy some 90 million light-years away. The dwarf galaxy Markarian 177 (center) and its unusual source SDSS1133 (blue) lie 90 million light-years away. The galaxies are located in the bowl of the Big Dipper, a well-known star pattern in the constellation Ursa Major.

Spiraling Light, Nanoparticles and Insights Into Life’s Structure Posted: 19 Nov 2014 02:48 PM PST As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented sugars ever make into life as we know it.

Physicists discover new subatomic particles Posted: 19 Nov 2014 01:09 PM PST Physicists have discovered two never-before-seen baryonic particles. The finding is expected to have a major impact on the study of quark dynamics.

Giving LEDs a cozy, warm glow Posted: 19 Nov 2014 08:24 AM PST When the 2014 Nobel Prize in physics was awarded this October to three Japanese-born scientists for the invention of blue light emitting diodes (LEDs), the prize committee declared LED lamps would light the 21st century. Now researchers from the Netherlands have found a novel way to ensure the lights of the future not only are energy efficient but also emit a cozy warmth.
